So ... I'm SMRT.
Dang near got me a Darwin Award tonight...
The wife was helping me move the air compressor in place. A 60gal monster that weighs a good bit. Well, we went to lift on it and some of the prepared piping that I'd put on was in the way (regulator, valve, quick release, elbow, etc).
Well I had to empty the tank anyway to hook up the new drainage stuff, so I had her hang onto that overflow valve chain while I losened the plumbing we needed out of our way...
After a couple minutes of waiting ... we were down to just under 40psi. My stupit head said "Oh that ain't bad, i can just undo the rest of this..." ... well "this" was the 3/4" main bushing into the tank ... that's right, i was about to open up a full 1" diameter hole in a 60 gallon tank at 40psi.
Well ... it was only 40psi, right? HA!
WOOSHHHHHHHHH ... it sent me a few feet away, with about 3lbs of plumbing kit in my hands. I'm glad i was wearin' gloves ... the ice woulda hurt. Yeah.
It prolly wasn't good on the tank neither ... Glad it was 'only' 40psi and not the 100+ it started at.
So there ya go .. lemme have it ...
